∙ 13y agox2-2x = 63
x2-2x -63 = 0 => x = -7 or x = 9
So x must = 9
Check: 92-18 = 63

∙ 13y agoNo, it is the discriminant of a quadratic equation.
No, not if the y is squared. When graphed the equation will not form a straight line.
The equation ax2 + bx + c = 0, where a != 0 is called quadratic.
Because it is in the form of ax^2+bx+c=0 Because quadratic means squared hence ax squared + bx +c=0 has a squared number as it's highest term. This is in fact the area of a square of a side "x" is x^2, so every equation having variable with exponent 2 become quadratic equation.

It is 22*54 = 2500.
First, you remove every x that you can from the equation. Next, you reach the simplest form of the equation, which is (7x-2)(x-2). Which is the lowest factorable form.

In the equation y x-5 2 plus 16 the standard form of the equation is 13. You find the answer to this by finding the value of X.
For a horizontal line, it is y= a value
expanded form
1st rearrange the equation so that it is in the form Y = . . . . .Then substitute in values for X (use whole numbers) and use the equation to calculate the value of Y (not Y squared).Then plot these numbers against each other (X and Y) on your graph.Remember that you also need to include negative values for X and when taking a square root the answer can be plus or minus (plot both), if you do enough examples you'll see a pattern forming
An equation of the second degree, meaning it contains at least one term that is squared.
Yes. Einstein proved this with his theory of relativity, and his equation, E=m c squared
